Shell Programming and Scripting

Hello everyone!!!! I am new to this forum ...I have a problem. And I thought that you are expert so you can help me with that... I have a text file with maaany lines. Every line begins with something like that:
<http aksjfskcuhrf kushkfsnus> <http sxnfrksehfsd gsdg r> I don't know if every line has two http beacause the lines are too many but I know that every line has at least two. I would like to remove these https and leave every line with whatever has next. I just want to remove these https from every line.
Also, I would like to choose random 10 lines from the modified file (without the https) and write them in a file.
I would be the happiest person in the world if you could help me with these problems...
thank you in advance!!!

something like

Code:

sed 's/<http[^>]*>//g' inputfile | tail +$(($RANDOM%$(wc -l <infile | xargs) )) | head >outputfile

omg!! thank tou very much for the quick answer!!!!
but I have a problem...

< < mplamplampla...

hmmm I think that I fixed it!! :

I had forgotten the < !!!! :P

Could you please provide an example of input you have,
as well as an example of output you expect ?

(ideally you can upload you file so people can make some test run with your real case and provide a more accurrate help to you.)

yeeesss I did it!!!
sed 's/<http[^>]*> //g' inputfile

I'm curious. Why pipe into xargs?

You want to remove whitespace at beginning of a line ?

Code:

sed 's/^  *//' inputfile >outputfile

You can gather it into one sed for example:

Code:

sed 's/<http[^>]*>//g;s/^  *//' inputfile >outputfile

@alister :

Code:

$ wc -l <myt
       2
$ wc -l <myt | xargs
2

But i suppose if you point it out to me, it just means that my xargs is useless because the simple calculation and expansion will remove the leading tab anyway ...

by the way, my code contains an error of logic :
if a file contains n lines, my random stuff could bring a number which is n-1 or n-2 ... so there are only 1 or 2 ... lines to tail (so my code would need some enforcement to make sure we really get at least 10 lines).
